Kakashi is playable character in Naruto:ultimate ninja heroes 2 and acts as Narutos sensei for the rest of the game.
Kakashi is the only son of Sakumo Hatake, also known as the White Fang of Konoha. His mother apparently died when he was young. Kakashi has been known since a young age as an extremely gifted prodigy, regarded by many as the best of his generation. He had received top marks and had showed an innate aptitude for the ninja arts while in the academy. This permitted him to graduate from it in a single year at the top of his class at the age of 5, and then becoming a chūnin a year later. Despite his own success, his father fell into disgrace after choosing to save his comrades rather than complete an important mission, causing Konohagakure to suffer in the war effort. Dishonored, Sakumo took his own life after a deep depression and a drop in his skills, which caused Kakashi to lead his life strictly by the ninja code.
After graduating, Kakashi was then teamed with Obito Uchiha and Rin under the leadership of Minato Namikaze, the future Fourth Hokage. Kakashi's relationship with Obito and Rin was noted to be very similar to that of Sasuke's relationship with Naruto and Sakura respectively, as he is known as the indifferent genius who shared a complicated relationship with his teammates, that later developed into a close friendship.
